Patented June 30, 1936 UNITED STATES PATENT OFFICE FAUCET 1 Claim.

The invention relates to faucets, especially faucets for liquids under pressure.

The object is to provide a faucet which will discharge the liquid without spurting or splashing.

The device is particularly adapted for controlling the fiow of beverages under pressure, when the same delivers to a mug or glass or similar receptacle, so that the discharging liquid will not splash.

It is known that, in such devices, where the valve opens directly into the discharge channel of the faucet, the liquid, upon the first break of the valve with its seat, spurts or issues in a jet which striking the bottom of the mug or other receptacle is liable to splash.

I have discovered that this objection may be overcome by providing a valve seat which is offset from the margin of the discharge channel, so that upon the break of the valve from the seat the liquid strikes a surface intermediate the seat and the margin of the discharge channel, thus breaking or bafiiing the spurt or jet. This results in an even smooth flow from the end of the discharge nozzle.

The invention therefore comprises such means, and other means in combination therewith, for controlling the discharge flow from the nozzle as herein described.

Referring to the drawing, which illustrates merely by way of example suitable means for the embodiment of my invention:-

Fig. l is a side elevation of a faucet in accordance with my invention.

Fig. 2 is a central vertical section of same.

Fig. 3 is an elevation of the valve element, at right angles to that shown in Fig. 2.

Fig. 4 is an underside plan of same.

Fig. 5 is a sectional detail on an enlarged scale.

Similar numerals refer to similar parts throughout the several views.

As shown in the drawing the faucet comprises the housing 1, having the cap 8 threaded on the top thereof, the nozzle element 9 threaded into the bottom thereof and the supply pipe l threaded into the side thereof and delivering into the chamber ll, formed in the housing. The nozzle element 9 is provided with a straight channel l2 from top to bottom and delivers from the chamber ll. Between the top of the nozzle element 9 and an annular flange [3, within the lower interiorly threaded portion of the housing 1, is clamped a valve seat I 4, which is preferably of medium hard rubber.

This valve seat It projects inwardly beyond the inner margin of flange IS. The inner margin of this seat It does not extend to the margin of channel I2, but is spaced back a substantial distance from said channel margin, as shown in Figs. 2 and 5.

A valve element 15, which is preferably rigid, has a convex lower end l6 for cooperation with the upper inner margin of valve seat element It. This valve element l has a yoke or upwardly extending recessed portion l1, and extending 10 above portion 11, is a post [8 extending into the sleeve or tubular part l9 projecting downwardly from the underside of the cap 8. The sleeve or tube l9 forms a guide for post 18. In an offset recess 20 of the housing is journalled a shaft 2! projecting through and having hearings in the lugs 22 formed on the wall of housing 1. This shaft 2| is connected on the outside of the housing to the operating handle 23. Mounted upon shaft 2|, within the offset recess 20, is an actuating arm 24, having a ball 24' on its outer or free end projecting into the recess 25 of valve element l5, and serves to communicate the movement of handle 23 to the valve element l5 to cause its vertical actuation. 25

The guide element 26 extends downwardly from the valve proper 16 of valve element l5, and is longitudinally fluted, as at 21, as shown in Fig. 3, to form liquid passages between said guide and the surrounding wall of channel I2. This guide 30 also cooperates with the bafiie between the margin of the valve seat and the margin of the nozzle channel, in modifying the flow as herein more particularly described.

It will also be noted that the supply inlet port 28, between pipe l0 and chamber H, is positioned above the valve 16 and valve seat element I4.

I n operation When the handle 23 is rocked in one direction, the valve I6 is lifted from its seat, and when rocked in the opposite direction the valve is closed. Due to the post l8 and cooperating guide tube l9, and the guiding element 26 having a slidable fit in the nozzle channel l2, the up and down motion of valve is vertical. This is permitted, without binding, by the loose fit of ball 24 in the circular or cylindrical opening 25.

When the valve I6 is seated, the pressure of the liquid in chamber II, and especially due to the valve body presented to said pressure, the valve is held upon its seat effectively to prevent any leak. The slight yielding of the medium hard rubber seat to the hard metal face of the valve, also contributes to the element to wear or distort is reduced to a mini mum.

When the valve is actuated to break from the seat, the break may not always be uniform or simultaneous throughout the circle of valve con= tact, but there may be a momentary first break at a portion ordy of the circle of content, when -the liquid is under pressure there is a tendency for the liquid to spurt at said point of first break, which causes a jet of liquid to strike the bottom of a receptacle which will cause the liquid to splash, which is wasteful and otherwise objectionable. This is the trouble with the conventional faucet now in common use.

I have found that by having the margin, as at I! of the nozzle bore or channel l2, positioned in advance of the inner margin of the valve seat, as at ll, as clearly shown in Fig. 5, or with the margin l4 spaced back a substantial distance from margin l2, a shelf or abutment or bafile 30 is provided, which encounters the spurt, indicated by the dotted lines 3| in Fig. 5, and breaks the jet before it enters the nozzle bore, the result being to overcome the objectional jet and splash, above referred to. That is to say, the liquid flows into and through the nozzle bore without undue velocity or objectionable violence.

The nullifying action upon the spurt or let as above described, is also augmented by the fluted walls of the element 26, since the lines of force of the jet or spurt, especially at the first break between valve and seat, are deflected or bamed before delivering to and from the nozzle 9. Thus we secure an even and smooth flow from the nozzle, irrespective of the pressure of delivery to chamber ll.

What I claim is:-

In an anti-splash faucet, the combination oi a body having a chamber with inlet and discharge openings, a discharge nozzle associated with said body and having a channel communicating with the said discharge opening, a valveseat member and a cooperating valve, the valveseat member comprising an annular body having an opening of diameter substantially less than that of the said discharge opening, and substantially greater than that of the nozzle channel, said valve-seat member having a thickness corresponding substantially to the distance between its inner margin and the margin of the said channel, thereby providing baffles in step formation between said discharge opening and said channel.
